Companies Drilling in the Duvernay Shale
- Duvernay Shale Stocks
Encana (ECA) - Encana ECA is drilling the Duvernay Shale and has provided an exploration update - In the Alberta Duvernay, where
Encana holds about 445,000 net acres, the company has drilled and completed three horizontal wells with lateral lengths
up to 6,300 feet. Encana has obtained core and reservoir data on each well and is encouraged by the results, which confirm
initial expectations. Each of the wells tested has flowed significant condensate volumes with favourable condensate to gas
ratios in line with other industry-announced results. Encana has two rigs drilling in the Duvernay.
Canadian Natural Resources (CNQ) - Canadian Natural Resources (CNQ) has 385,000 acres in the Duvernay Play - As far
as the Duvernay, our plans go, we'll likely drill
one well, to sort of prove up some of our lands. But we are, as you know, fairly bearish on gas, we have large inventories
on oil sites, so it's not like we have to drill up our gas prospects or liquids-rich gas prospects. So we're probably going
to be, I would say, someone who watches what's going on and take the advantage of being a second mover.
Trilogy Energy (TET) - Trilogy Energy (TSX:TET) is very active in the Duvernay Shale - Trilogy managed the
drilling, completion and tie in operations for the second horizontal well targeting the Devonian Duvernay shale formation
under a previously announced joint venture with Celtic Exploration Ltd. and Yoho Resources Inc., pursuant to which each partner
has a one-third working interest in 30 gross sections of land. The well (the “3-13 well”) was drilled from a surface location at 16-14-60-20W5 to a bottom
hole location at 03-13-060-20W5, with a total depth of 4,866 meters. The horizontal lateral was 1,391 metres in length within
the Duvernay formation. Completion operations began March 8, 2011 and were concluded in late April. The well was fracture
stimulated in 31 perforated intervals in 12 separate stages along the length of the horizontal wellbore. In total, approximately
2,300 tonnes of sand and 138,600 barrels of slick water were used to stimulate the well. The well was completed using a staged
“plug and perf” horizontal completion technique, incorporating perforation clusters (2 and 3 per stage) to stimulate the well.
Following the fracture stimulation, the plugs were drilled out to permit the well to flow without obstruction in the horizontal
portion of the well.
The 3-13 well was tied-in April
10, 2011 and was flowing up 7 inch casing and had initial production of approximately 1,250 Boe/d. Production tubing was installed in the well and the well has been
placed on production to evaluate the longer-term production performance of the play. Additional analysis is required to determine
the production composition, including the natural gas liquid content, from this Duvernay shale exploration play. However,
initial production to date has indicated that the natural gas liquids content is higher than originally expected and may contain
up to 90 barrels per MMcf of condensate plus additional associated natural gas liquids recovered at the gas plant. Additional
work is required to further understand the reservoir to optimize natural gas liquids recovery and maximize the rate of return
for the wells.
Trilogy is encouraged by the results from these two horizontal Duvernay shale wells and particularly
the high liquids content. Trilogy is evaluating opportunities to further evaluate its Duvernay land holdings in
the Kaybob area and will continue to monitor industry activity directed towards the exploitation of the Duvernay shale. Trilogy
currently owns approximately 163,129 gross acres and 132,813 net acres (255 gross sections and 207 net sections) of land with
Duvernay rights at Kaybob and surrounding areas.
Talisman Energy (TLM) - Talisman Energy (TLM) Duvernay Shale Update - And we took a substantial position in the liquids-rich Duvernay shale here in Alberta, which we will learn a lot more about in the next 12
months as we continue to pilot. Talisman plans 6 wells in the Duvernay Shale. , it's clearly very early days in
the Duvernay for us and would be for the industry.
We've drilled 2 wells now, and we're literally probably a number of days away from completing our first well. It's tied in
and we'll be seeing our very first -- our own very first Duvernay
results in the next few weeks. As John has said, we'll be drilling an additional 6 wells this year. I'll just remind everybody
that we're in a fairly large position, a split between what we call the northern and the southern parts of the Duvernay play, about 350,000 acres, and so those 6 wells are going to make a small
dent on de-risking the 350,000 acres within the play. We think that's the natural pace to go, so that we can alternate wells
between the north and the south as we de-risk the play this year.
2012 Update - In the liquids-rich Duvernay, we drilled the second well of a six-well pilot program.
ConocoPhillips (COP) - ConocoPhillips (COP) is active in
the Duvernay Shale but isn't talking about it that much just yet. Stay tuned for updates.
Chevron (CVX) - Chevron (CVX) is active in
the Duvernay Shale located in Canada. Chevron (CVX) announced in October 2011 that they are drilling their first well
in the Duvernay Shale right now. More details will be provided at a later date.
